I had always been skeptical about electric toothbrushes but after using Oral B Genius 8000, I will definitely never go back! I have been using Oral-B products for the last 10 years but Oral B genius is top of the range quality! I really like the fact that it connects via Bluetooth to your smartphone where through an app, you can personalize your brushing experience with the help of face recognition. In addition, you have the option of using different toothbrush heads in order to cater for your own needs. I can't forget to mention how powerful is the brushing! Your teeth would feel like just after a visit to the dentist.It has a long battery life and it changes colour if you press too much on your teeth. I highly recommend it as it is very easy to use and if you're willing to a properly look after your teeth, then Oral B Genius is a must!
